2 Stroke

[Stevie J]

Hi all,

Now i have my Delta with a 125 HP petrol eater I'm just as happy as can be.

Being a 2 Stroke engine, I need to add that rediculously priced stuff into my costs too.

What are your opinions of this stuff...

2T OUTBOARD MARINE TWO 2 STROKE OIL TC-W3 API TD 5 LTR BIO OIL MARINE SAFE | eBay

...£40 for 10 litres, as compared to the twice the price stuff offered from the more mainstream marine suppliers? (last lot was £31 for 4 litres)

I do come from the school of "2 Stoke is 2 Stroke is 2 Stroke", the stuff that goes in lawn mowers does the same as in motorbikes as it does in outboards. But I've been a good boy and used marine stuff in my outboard. Just looking for the best bargain out there.

Cheers Stevie

Outboard two stroke oil IS different than the two stroke oil you would put in garden machinery and chainsaws. These items are air cooled and you outboard is water cooled, the oils are designed to work at different temps.

As for the oil in your link, it may be tcw3 spec but I'd still stick with a recognised brand but that's just me.

[Stevie J]

Thanks for that.

Any other contributors?

how many hours do you do per year?

[matt h]

As long as its TCW3 ..

I've run a seagul on that. Figured if I was running on 1:10 the least I could do was make it a bit greener...

You need TC3W it works at different temp to air cooled engines.

You may find some of the more expensive oils are designed for autolube systems etc so have other requirements as well as being TC3W ... Are u autolubing or premixing?

[Stevie J]

It is an autolube and so far I'm doing up to 20 hours a month.

How much fuel do you burn?

Are you planning a newer engine anytime soon?

i had a mariner 100 4 stroke and it was circa 0.6 lpm at 22 knots for reference.

Even then, not all 2 stroke oils are equal. I had a strimmer that used to "grip" when it was running hard. I asked a mechanic about it - fearing the end was nigh, and he said - I bet you use forecourt 2 stroke - i.e. for motorbikes. I did. He recommended Stihl or Jonserd oil and the machine never looked back.

I ran at 20 to 25 (ish) Knots for 38 NM and used 48 litres, last weekend.

1.21 litres to the NM or 0.83 NM to the litre.

Still feeling my way to the optimum spedd to fuel ratio.

Have a long term plan to try twin 4 stroke 60s at some point either with this boat or the next. Did look a buying a twin set up rib this time but the budget wasn't healthy enough.

Keep an eye out for offers

With the hours you are doing I would call about and get a deal for as many gallons as you need for a season if you have somewhere to keep it.

Personally I would buy branded marine 2 stroke rather than generic stuff due to the miles you are doing.
